Problem with DVD Shrink Guide

The guide for Says that after you select the disc the analysis will run, it then says to make sure the "Full Disc button" is pressed.
Where is that blasted button?
I can't find it anywhere.
I'm using version 3.0 Beta 5.

dvd shrink work great, i dont think they have got a new guide out for beta 5 no full disk button. not only can you put in what you want but its free! some movie have neat things at the beginning for thx i put those in before the movie when reauthoring
